When most people think about monitoring HIV progression they think of CD4 testing. CD4 tests show the relative strength of the immune system. These tests are usually simple to perform and inexpensive to run so they are widely available. But to manage HIV, doctors also need to know how active the virus is. CD4 tests cannot provide this information. To determine viral activity, doctors need to run an HIV viral load test. While viral load testing is a routine part of HIV management in developed nations, it is often considered too expensive and complicated to be used elsewhere. ExaVir Load was designed to address this problem. It provides highly accurate viral load results with a test that can be run with just a basic lab set-up. Better yet, it can detect all HIV types and subtypes.
Viral load and ART
Antiretroviral therapy (ART) is becoming increasingly available to people in resource-limited settings. In order for doctors to make the most of these drugs, they must be able to manage their use. While CD4 is an excellent tool for seeing how the body reacts to HIV, it is less helpful to see how the virus is reacting to ART. That is where viral load testing excels. It allows doctors to observe HIV activity directly. And with ExaVir Load, doctors can monitor activity in all known HIV types and subtypes. Viral load testing helps the doctor know when to start ARV therapy and when to switch drugs that are no longer working. This can help prolong a patient’s productive years, make ARV supplies go further and help slow the emergence of drug-resistant HIV strains.
